“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a five year period?

Today, let’s look backwards in time to 2020, and take a look at what happened to investors who asked that very question about Union Pacific Corp (NYSE: UNP), by taking a look at the investment outcome over a five year holding period.

Start date: 03/31/2020
$10,000

03/31/2020
  $18,338

03/28/2025
End date: 03/28/2025
Start price/share: $141.04
End price/share: $232.15
Starting shares: 70.90
Ending shares: 79.01
Dividends reinvested/share: $24.10
Total return: 83.41%
Average annual return: 12.91%
Starting investment: $10,000.00
Ending investment: $18,338.89

The above analysis shows the five year investment result worked out quite well, with an annualized rate of return of 12.91%. This would have turned a $10K investment made 5 years ago into $18,338.89 today (as of 03/28/2025). On a total return basis, that’s a result of 83.41% (something to think about: how might UNP shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Union Pacific Corp paid investors a total of $24.10/share in dividends over the 5 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 5.36/share, we calculate that UNP has a current yield of approximately 2.31%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 5.36 against the original $141.04/share purchase price. This works out to a yield on cost of 1.64%.
